感谢 但是我配置了使用怎么都不起任何作用，errors参数始终为null，在nutzwk-mvc-chain.json中也配置了ValidationProcessor，麻烦看一下

 @At("/getUserInfo")
    @Ok("json")
    public Object getUserInfo(@Validations(required = true, errorMsg = "userid is required")String userid, @Param("clientId")String clientId, Errors errors) {
        try {
            //Subject subject = SecurityUtils.getSubject();
            Sys_user curUser = sysUserService.fetch(userid);
            if (curUser != null) {
                return Result.success("system.success", sysUserService.getUserInfo(curUser,clientId));
            }
            throw new ValidatException("参数不正确!");
        } catch (Exception e) {
            e.printStackTrace();
            return Result.error("system.error", e);
        }

    }

var chain={
	"default" : {
		"ps" : [
			  "cn.wizzer.app.web.commons.processor.LogTimeProcessor",
			  "cn.wizzer.app.web.commons.processor.GlobalsSettingProcessor",
			  "org.nutz.mvc.impl.processor.UpdateRequestAttributesProcessor",
		      "org.nutz.mvc.impl.processor.EncodingProcessor",
		      "org.nutz.mvc.impl.processor.ModuleProcessor",
              "cn.wizzer.app.web.commons.processor.NutShiroProcessor",
              "cn.wizzer.app.web.commons.processor.XssSqlFilterProcessor",
		      "org.nutz.mvc.impl.processor.ActionFiltersProcessor",
		      "org.nutz.mvc.impl.processor.AdaptorProcessor",
		      "org.nutz.mvc.impl.processor.MethodInvokeProcessor",
			  "org.nutz.mvc.impl.processor.ViewProcessor",
			"org.nutz.plugins.validation.ValidationProcessor"
		],
		"error" : 'org.nutz.mvc.impl.processor.FailProcessor'
	}
};

好啊 找个时间研究一下
